Due to the special surface treatment of the bearings, there may be slight deviations from the standard tolerances. These deviations do not affect mounting or bearing operation.

Housing bore has an increased sphere diameter appropriate for high temperature applications.

Due to the special surface treatment of the bearings and Y-bearing unit housings, there may be slight deviations from the standard tolerances. These deviations do not affect mounting or bearing operation.

≈ 20 to 30 minutes of arc
The above values apply only when the bearings rotate slowly. The permissible angular misalignment between the inner and outer ring depends on the size and internal design of the bearing, radial internal clearance in operation and the forces and moments acting on the bearing. As a result, only approximate values are listed here. Any misalignment increases bearing noise and reduces bearing service life.

≈ 20 to 30 minutes of arc

Initial misalignment ≤ 5°

Stabilization

120 °C (250 °F)
The rings, rolling elements, cages and housings of SKF high temperature Y-bearings and Y-bearing units undergo the same heat stabilization process as the relevant standard Y-bearing and Y-bearing unit. As a result, for higher operating temperatures, a certain amount of dimensional change is to be expected. For additional information, contact the SKF application engineering service.
